OWINGS MILLS, Md. — The roster additions kept coming Wednesday afternoon as the Ravens added former Buffalo guard Cord Howard to build depth along the offensive line at the start of training camp.

An undrafted free agent from Georgia Tech in 2010, Howard spent his rookie season in Buffalo before spending last season on injured reserve with a shoulder injury. He played in 10 games and started four for the Bills during his rookie season.

The 6-foor-4, 314-pound guard is likely a depth move for training camp as the Ravens now have the maximum 90 players on their preseason roster.

Howard joins linebackers Ricky Brown and Darryl Blackstock as roster additions on the eve of the first full-squad workout scheduled to take place on Thursday afternoon.
